The paper presents an example of an economic subsystem of CD focused on the economical optimization of NBs with an emphasis on the circular economy. It also demonstrates the significant potential of NBs to improve the architectural visual appearance of built-up areas as essential spatial elements and improve the microclimate of their surroundings. The authors focused on comparing the costs of construction of NB with acoustic elements made of the most used materials in the Slovak Republic: aluminium, chipped cement, transparent NB, and NB made of recycled plastic. The comparisons show that the most cost-effective option is a noise barrier made of recycled plastic. Despite the higher cost, its higher sound absorption and the environmental durability of the acoustic elements are decisive. The use of secondary raw materials is also a significant advantage of CD. Waste plastics, mainly from municipal waste, are used for production, making it possible to recycle 100 % of them again.","PeriodicalId":42034,"journal":{"name":"Civil and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45456354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has a direct impact on the innovation of renewable energy technology and its application in building industry. In accordance with the requirements of the “Europe 2020 Strategy” and “Europe 2030 Project”, the long-term goal is to achieve the maximum use of renewable energy sources in the buildings´ operation. One of the solutions is the building-integrated photovoltaic power plant. The paper analyses efficiency and incorporation of photovoltaic (PV) systems into the roofs and perimeter walls. PV systems are a renewable energy source used in the construction of zero energy buildings producing minimal environmental pollution. Semi-transparent building-integrated photovoltaics (BIPV) are one of the technologies that have the potential to increase the building´s energy efficiency as well as aesthetically complete the building´s design. The paper deals with material characteristics of PV panels in terms of the fire risk and definition of the fire hazardous area that arises during their combustion. It is focused on the incorporation of various types of PV technology into the facades and roofs, structural and material solutions of fire-dividing structures to which PV systems are fastened considering their location in the fire hazardous area. Based on the external fire simulations, conclusions in this paper bring the optimal position of PV systems in the building envelope in relation to fire open areas, fire lines and fire hazardous areas. The safety of firefighters during the intervention also depends on the position of PV systems. The case study presented in this paper uses a model solution to give the optimal position of PV systems in the building envelope considering the fire safety.","PeriodicalId":42034,"journal":{"name":"Civil and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47164751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are composed by elements of different dimensions (from a few microns to tens of centimeters), and can be of very varied nature (clay, sand, gravel, pebbles, etc.). The mechanical characterization of coarse-grained soils is very difficult because of the presence of large elements. In order to be able to characterize them in the laboratory by means of conventional size devices, it is very important to study the influence of significant parameters on the mechanical behavior of coarse-grained soils (the volume fraction, particle size distribution and spread, consolidation level and initial state of the matrix), using the large-sized triaxial testing device. In this paper, we will propose a methodology for evaluating the mechanical characteristics of coarse-grained soils based on soil granulometric reconstruction procedures. The method we have named GALA is based on the use of polynomial correlations between the strength increase due to inclusions and the volume fraction fv and the particle spread (dmin/dmax) of inclusions. We were able to apply this new method to a natural soil. The results showed the relevance of our method.","PeriodicalId":42034,"journal":{"name":"Civil and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47230998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings of a cross-sectional study - a questionnaire survey of residents living in newly built apartment houses in some Slovak towns (Bratislava, Trencin, Martin, Piestany) are presented in this paper. The average age of the 543 respondents was 45 ± 4 years, 53 % were females, and 81 % had lived in their current home for more than five years. Traffic noise measurements on noisy facades LAeq,day = 51.8 dB to 72.4 dB, LAeq,night = 41.9 dB to 64 dB were supplemented by a standardized questionnaire. In comparison to respondents with bedroom windows facing quiet streets, those who face noisy streets are less satisfied with their quality of life, less sensitive to noise, and more irritable and restless during the day and night OR = 2.54; 95 % CI = 1.38-4.92. After the results have become completed, we hope to suggest temporary solutions for noisy apartment building facades, as well as intervention techniques, and to apply sound city planning principles.","PeriodicalId":42034,"journal":{"name":"Civil and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46271533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
